IMPROVEMENT IN FLUTlNG-MACHINES.

Specification forming part of Letters Patent No. 218,696, dated August19, 1879; application filed March 31, 1879.

To all whom it may concern:

Be it known that I, HERMANN ALBRECHT, of Philadelphia, Pennsylvania,have invented a new and useful Improvement in Fluting- 'Machines, ofwhich the following is a specification.

My invention relates to improvements in fluting-machines in which one ofthe flutingrollers is carried by a movable frame and the other by afixed frame; and my improvements consist in a certain combination,described hereinafter, of an upper fluting-roller adapted to fixedbearin gs with a rocking frame carrying the lower roller, and having atable for receiving the fabric, and permitting the proper presentationof the same to the rollers, my improvements further consisting ofdevices, described hereinafter, for imparting an upward pressure to therocking frame.

In the accompanying drawings, Figure 1 is a vertical section of myimproved flirting-machine; Fig. 2, a sectional plan on the line 12, Fig.1; Fig 3, a view of the outer end of the machine, looking in thedirection of the arrow 1, Fig. 1, Fig. 4, a view of the opposite end ofthe machine, looking in the direction of the arrow 2, Fig. 1; Fig. 5, avertical section on the line 3 4, Fig. 1; Fig. 6, an inverted plan view,and Fig. 7 a perspective view, of the rocking frame which carries thelower flutingroller.

A is the base of the machine, and to the top of this base, near one endof the same, is secured the frame B, of which the projecting arm B (bestobserved in Fig. 1) forms a part.

The upper fluting-roller, D, has one of its bearings in the frame B, andits other bearing in a lug, a, secured to the outer end of theprojecting arm B.

The lower fluting-roller, D, is carried by the pivoted rocking frame Gr,a perspective view of which is shown in Fig. 7. This frame has two pinsor trunnions, b I), having bearings in projections cl (1 on the base,and the front portion, 6, of the frame is the platform or table on whichto place the fabric to be submitted to the action of the rollers.

There are two bearings, f f on the rocking frame, the former for theouter journal of the lower fluting-roller, and the latter for the innerjournal of the same, this inner journal being continued outward from itsbearing, so as to receive the handle H.

An arm, h, projects downward from the rear of the frame G through a slotin the base A, and the end of this arm is connected by a spring, 1', toa lever, m, which is pivoted at n to the under side of the base, thelong arm of the lever being under the control of a screw, 1), by turningwhich the spring may be caused to raise the rocking frame and press thelower roller against the upper roller with more or less force, ascircumstances may require.

In order to depress the rocking frame and lower roller, and maintain thelatter at a distance from the upper roller when required, I pivot to alug, q, on one end of the said rocking frame a cam-lever, M, which is inthe position shown in Fig. 5 when the rocking frame is raised to itsfull height and the lower roller is in forcible contact with the upperroller; but on depressing the arm :0 of the lever its cam 5: bearingagainst a shoulder on the frame B, will cause the depression of therocking frame, the cam being such as to retain the frame in a depressedcondition until the arm as is elevated. By this device the lower rollerand table may be maintained in such a position as to enable the operatorto adjust the fabric properly before it is confined between the rollers.

The cam-lever may, if desired, be pivoted to the frame B, the cam inthis case bearing on the rocking frame.

A slight separation of the rollers, sufficient to permit the adjustmentor removal of the fabric, may be effected by simply pressing down uponthe table 6 of the rocking framean operation which can readily beperformed, as the hands rest upon said table while the fabric is beingfed to the rollers D D.

I claim as my invention 1. The combination, in afluting-machine, of thebase A, the frame B B, carrying the upper roller, the rocking frame G,carrying the lower roller, pivoted in the rear of the same, and havingin front a table, a, on which to place the fabric, and devices whereby ayielding up In testimony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.

HERM ANN ALBRECHT.
